Bug: Unrar stops because of low diskspace, doesn't continue after more diskspace is freed. Even not after restarting the program.
I was downloading. There was only 2GB free diskspace.
After parring, alt.binz began unpacking a dvd. After a while diskspace was low. Alt.binz stopped downloading (that's ok). I freed up an extra 5GB of diskspace. Alt.binz continued downloading. But the unrar didn't continue unpacking, even after restarting alt.binz.
